7.4.1.2 Flush Mounting
Flush-mount shelves are mounted on the back of the posts. The equipment is placed on the
shelf and secured to the front of the rack posts using screws appropriate for your particular
rack. Flush mounting is permitted in two-post racks that have been reinforced with wall
supports.
7.4.2 Four-Post Shelf Kit
The four-post shelf kits allow the E-Class/F-Class components to be mounted in a variety of
four-post racks and rack cabinets. The shelves can either be front-and-rear mounted
(preferred) or side mounted depending on the style of rack. Each enclosure requires its own
mounting kit. Stacking one enclosure on top of another is not permitted.
7.4.2.1 Front and Rear Mounting
Four-post shelves are mounted to the front and rear rails of a four-post rack. Each side requires
two shelf halves and the corresponding mounting hardware. The shelf halves are expandable
to fit racks of different depths. Front shelf halves have left and right pieces, while the rear
shelf half can be used on either side of the rack. The E200 and F200 controllers use a 4U shelf
kit (the F400 uses an 8U kit), and drive chassis use a 3U shelf kit. For service processor
mounting, refer to the instructions included with the 3PAR Service Processor rail kit.
When both the left and right side installation is complete, the equipment can be placed on the
shelves and secured to the RETMA (Radio Electronics Television Manufacturers Association)
rails. The following figure shows the spacing standard of RETMA rails.
7.4.2.2 Side Mounting
Though front-and-rear mounting is preferred when possible, the four-post shelves can be
mounted to side rails which have RETMA-spaced #10-32 tapped holes. Each side requires two
shelf halves and the corresponding mounting hardware. The shelf halves are expandable to fit
racks of different depths. Front shelf halves have left and right pieces, while the rear shelf half
can be used on either side of the rack. The E200 and F200 controllers use a 4U shelf kit (the
F400 uses an 8U kit), and drive chassis use a 3U shelf kit. For service processor mounting, refer
to the instructions included with the 3PAR Service Processor rail kit.
Once the proper location is determined, each shelf half is mounted to the side rails of the rack.
The shelf halves are secured to the rack and to each other using pan head screws. When both
the left and right sides are complete, the equipment is placed on the shelves and secured to
the front rails.
